To a/ZZ whom tlm/wy concern: i I Be it known vthat I, WILLIAM P. WELD, Va

. citizen of :the United States, residing at Marianna, in lthe countyofLee and State of Arkansas, have invented ,a new and useful Gin-Roll ABoard and Feeder, of which the .following is a specification.

This -inventlon lrelates to feed-regulators forgins g and its Object isfto provide a device of this character ha-ving means for 4controlling 1thero.tation ofthe feed-wheel in ropor- Ltipn to ,thesizeofthe cotton roll witiiin the vgilll; 4 v' v l l A still further .object is Lto .provide a roll- 4board `which is movably connected to the ,gin and isadapted to regulate 4the positions ofthe feed-pawls. c 1 l.Another object is to kprovide a roll-board having means whereby the ycotton roll is visible at alll times, thereby permitting Athe scorching of thecottonfcc., to be easily detecfed- 4 f A furtherobject is to Iprovide a roll-'board which can .be quickly detached, so as to enablethefentire cottonroll to be removed from thegin, `if desired.

With the aboveand other objects in view the inventioniconsistsofa guide onwhich are mounted slides vhaving a springepressed varm ymeans whereby the sl-ides may be quickly removed from the guide, so as to permit the entire cotton roll to .be dumped, if desired.

The :invention further consists in providing a glass strip within the roll-board, so that theroll will .be visibleat all tim es to the o erator, who can therefore readily detect t e scorching of the cotton,-&c. l

The invention also consists of certain other novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims,

In the laccomp anying drawing is shown the preferred formvof the invention.

Said drawing :is a lperspective view of a portion of a ,gin and showing the invention applied thereto.

Referring to'thedrawing, 1 is agin having a roll-board`2 disposed infront of ,the roll- `b ox- 3, and .in .theroll-:board .isdisposedtast'rip offglass 4, whereby `the cottonl roll is :rendered visible at l.all times lto the operator. Extending `from the roll-board Iis 4anarm 6, which is slidably mounted Within-vafblock 7, mounted upon .and engaging a .channeled guide 8, `Which Iis karranged on Athe zgin. This vguide is formed with teeth 9, radapted *to ibeengaged by avpawl 1,0 `upon the block. .Another block -1-1 is slidably mounted ,non :the guide 8 and has fathreadedopeninglZ,theref through, into which is screwed ithe threaded end 13 of the arm 6. .A nut 14ismountedon the `threaded portion ofthe armvandfisadapted tcl)i clamp Aa coiled spring 1,5 against the bloc 7.

A T-shaped lever` 16is centrallyfulcrumed uponone side oftheguide 8 .and the ,depending arm, and ythis lever .isrconnectedby means of a rod 17 with .the yforward `end of arm 6. The gin -is rovided ywitl'vtheusual vratchet-wheel 18, w 'ch isconneoted to the feed-cylinder,- (not shown) and tthis v.ratchetwheel is engaged by two pawls 19 and120, fthe pivot-pins 21 and 22 of which are :mounted .1n slots 23, disposed longitudinally within a lever 24 at opposite sides fof the fulcmirn 25 thereof, This lever is adapted to vbed-riven by a pitman 26, which is connected .to V,one

end thereof and `to a drive-shaft 27'.. 'The' ends of the pawls 19 and 20 Aextend beyondl the lever, and one end of the paWl 419 is secured to one end of lever 16 by ymeans of a rod 26, while the other end of lever 116 .isconnected by a rod 27 to one end of the pawl 20.

In operation the cotton is fed into the rollbox 3 in any desired manner, this being caused by the rotation of thevratchet-wheel 17. of lever 2,4 and thealternate engagement lby the pawls with the lever. The yspring 15 serves to hold the .roll-board 2 normally .in a

Said wheel is rotated by the actuation' predetermined relation with the box 3; lbut should the cottonroll become-of too large proportions the roll-board will be pushed outward and will cause the arm 6 to slide longitudinally, thereby compressing the 'spring 15.. This longitudinal movement ofthearrn will cause rod 17 to pull -on the depending .arm of lever 16, and as a result the upper pawl 19 will be drawn toward the fulcrum 25,

IIO

while the lower pawl 20 will also be pushed toward said fulcrum. The strokes of these pawls will thus be materially diminished and the rotation of the ratchetwill be correspondingly reduced. Should the outward movement of the roll-board continue, the lever 16 will pull further on the pawl 19, so that its fulcrum 21 will bear against the lower end of the upper slot 23, and said pawl will therefore be swung entirely out of engagement with the ratchet-wheel. The movement of said wheel will thus be practically stopped, because it will be actuated solely by the lower pawl, and the stroke of said pawl will be so short that in view of its proximity to fulcrum 25 it will practically leave the ratchet-wheel stationary. The supply of cotton to the rollbox will thus be practically cut off, and as the roll diminishes the springl will return all of the parts to their normal positions and the rotation of the ratchet-wheel 17 will gradually increase. Should the cotton roll become scorched or should dents appear within the roll, the same can be readily detected through the glass 4, and, if desired, the entire roll can beremoved bylifting the pawl 10 and withdrawing the two blocks 7 and.11 from the guide 12. It will of course be necessary to detach the rod 17 from lever 16.

The preferred form of the invention has been set forth in the foregoing description; but l do not limit myself thereto, as l am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and l therefore reserve the right to make such changes as fairly fall within the scope of the claims.
